WINDOW.

SPECIFICATION forming part of Letters Patent No. 460,449, dated September 29, 1891.

Application filed May 9, 1891. serial No. 392,199. (No model.)

To all whom, it may concern.-

Be it known that I, VALENTINE SCHIRMER, of New York city, in the county and State of New York, have in vented new and useful In provements in WVindows, of which the following is a full, clear, and exact description.

The objects of this invention are to provide simple, practical, and inexpensive improvements for windows, which will afford means I0 to open the window by swinging the sash both within the apartment lighted thereby and also enable the sash to be slid vertically and independently, as usual, the swinging adjustment being provided to facilitate the cleansing of each side of the upper and lower sash in a convenient and safe manner.

To these ends my invention consists in the construction and combination of parts, as is hereinafter described and claimed.

2 Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is an inner side elevation of a win 2 5 dow-frame and its upper and lower sash embodying the improvements, the sash being closed. Fig. 2 is an inner side elevation of a window-frame broken away on one side and two sash therein held in a novel manner.

3 Fig. 3 is an enlarged plan, in section, on the line 3 3 in Fig. 2, showing the sash in swinging adjustment by dotted lines. Fig. at is an enlarged vertical section on the line at 4 in Figs. 2 and 3. Fig. 5 is asectional side view of a portion of one side of the casing or window-frame, taken on the line 5 5 in Fig. 3. Fig. 6 is a sectional side View of a portion of one side of the window-casing, taken on the line 6 6 in Fig. Fig. 7 is an enlarged 4 detached view of one of two similar pieces preferably employed to adjust the parting strips between the window-sash and enable said sash to be swung from one side of the easement or window-frame. Fig. Sis a sectional View showing an enlarged broken detail of construction, taken on the line 8 8 in Fig. 2 and viewed in the direction of an adjacent arrow. Fig. 9 is a transverse section of one side of the window-casement, taken on 5 the line 9 9 in Fig. 4. Fig. 10 is a detached enlarged view of an improved rope-sheave and its frame preferably employed in connection with the sash-supporting ropes and window-casement.

The improvements which are the subject of this invention may be applied to any window of the ordinary type wherein the sash is counterbalanced with weights and suspended by ropes or cords thereto attached.

A represents a window-casing provided 6c with boxes, wherein the counterbalanceweights may slide vertically, said boxes where shown being indicated by the letter a. Two sashes B O, that are respectively the upper and lower sash of the window, are held to slide vertically in the frame A by the outer bead-strips b, inner bead-strips o, and center or parting strips d, the strips 0 and d being peculiarly constructed, for purposes that will appear. Each parting-strip d is separated into two sections near its center, and, as represented in Figs. 5 and 6, the adjacent ends of such sectional strips cl are notched and pointed to mate each other, the loosely-fittin g pointed end d of a lower strip-section entering the notch d of the upper strip-section, so as to check the lower sections from entire removal from the grooves in the easement A, wherein they are seated. On the lower end of each lower parting-strip section similar notches d are cut, wherein the tongues d similar in form to the pointed 'ends (1, are inserted. The lower partingstrip sections mentioned are reduced in width as compared to the upper strip-sections, of which they are continuations, to permit the lower strip-sections to be moved outwardly and align their outer edges with the outer edges of the upper strip-sections or be retracted within the grooves they are seated in, so as to align their outer edges with the faces of the windowcasement, whereon the side edges of the window-sashes loosely impinge. As a preferred means to slide the lower sections of the parting strips din the manner just explained, the 5 similar cam-shafts e are provided, (see Figs. 3, 5, 6, and 7,) which have a location at any proper point in the side walls of the window frame or casement, entering perforations made through the lower parting-strip sections laterally, there being an eccentric formation e on each shaft-body, which is seated loosely in an aperture in the strip-section to be moved, which engagement of parts will permit the outward projection of thelower parting-strip sections when the cam-shafts c are partly rotated in a proper direction and a retraction of said strip-sections if the cam-shafts are given a reversed rotative movement.

As shown in Fig. 8, the camshat'ts e are perforated opposite an open slot g, that is formed in the stiles of the window-casing A, said transverse holes f (see Fig. 7) being designed to receive the end of a small pin-lever h, which, when inserted, will afford means to partly rotate each shaft and throw its eccentric 6' into the position indicated in Fig. 5, thus projecting the lower strip-section, as therein shown, said strip-section being in a retracted condition in Fig. 6. At the end (2 of the cam-shaft e the body of the shaft is squared to receive a socket key or crank 2', as shown by dotted lines in Fig. 8, which will permit the shafts e to be turned from the innor side of "the window-frame A when it is desired, this latter being the preferred means for manipulating the cam-shafts.

On the left side of the window-casement A the sashes B C are supported to slide by similar weights K, one being shown in Fig. 2. Said weights, of usual form,sliding in the boxes 0. of the window-casing, are connected flexibly to the sash, the cords each passing over ordinary sheaves or grooved pulleys at the tops of the boxes. The opposite side edges of the sash B O are each sustained by a cord m, which cords have one end of each attached at m to the edge of the sash it supports, and thence extends upwardly, as shown in Fig. 9, passing over the sheave-wheel n, that is rotatably engaged with a bracket-frame n. The latter named,projecting across the box a, has its inner end inserted in the walla of the box, so as to be retained in position. The sash-cords an, after passing through the similar sheave-bracket frames 02', are caused to engage the grooved pulleys 0' of the weights 0, one being shown in Fig. 9, and then ex tended upwardly to be attached by their remaining ends to the bracket-framesn within the weight-boxes a.

The provision just mentioned is made to facilitate the swinging movement of both sashes, as will be further explained.

The lower sash O of the window is hinged at p 19' above and below on the left side of-the windowcasement, preferably, so as to permit it to be swung into the room, as indicated by dotted lines in Fig. 3, and to allow such an adjustment of parts to be efiected readily the inner bead-strips c on each side of the casement A are severed at about their center, as shown at q in Fig. 4, the upper portion having a rigid attachment upon the inner surface of the sides of the window-casement, so as to loosely bear against the lower sash when it is slid upwardly. It should be further explained with regard to the hinged connections of the lower sash C that these hinges are of the hook-and-eye type, wherein a depending pintle on the hinge-leaf, that is secured on the sash, engages. an eye 011 the other leaf that is attached to the stile of the easement, so that the aligning pintles of the two hinges will slide into the eyes when the lower sash is lowered after being raised, the hinges being separated in their parts by the elevation of the sash 0. Below the points q the lower parts 0' of the bead-strips c are hinged by one edge of each to the easement sides, so as to allow these parts of the strips to fold inwardly, as shown by dotted lines in Fig. 3, or be swung outwardly, as indicated by full lines in the same figure. XV hen the swinging beadstrip sections 0 are folded inwardly, they may be secured in alignment with the fixed upper portions of the bead-strips they form a part of by slide-bolts 0 that are embedded in the fixed portions of the strips, so as to latch fast to the swinging parts by spring action, if desired.

On the window-sill A a keeper-strip ois hinged, which, like the swinging portions 0 of the bead-strips c, is designed to fold inwardly or toward the lower sash C and close the crevice at the lower edge of the latter, there being a rabbet-edge produced at 0 0" on the bead-strips and keeper-strips, respectively, which engage shoulders on the windowstiles and window-sill, so as to break the joints and prevent direct air-currents from entering the room lighted by the window. The keeperstrip 0* is retained in position folded inwardly, when the folding bead-strip sections 0' are similarly adjusted, by a sliding bolt r located on each swinging beadstrip at its lower end, as represented by dotted lines in Fig. 4.

The upper sash B is furnished with hooks s, that will slide into pockets formed in the top rail of the lower sash when the upper sash is lowered completely, as shown in Figs. 2, 3, and 4., whereby the weight of the upper sash may be imposed upon the lower sash and the upper sash moved along with the latter-named sash if the counterbalance-weights on the right side of the easement A are so supported as to allow the sashes to rest 011 the hinges p p.

In order to permit the free inward movement of the lower sash C and supported sash B on the hinges p 1), there is a belaying bracket-bar a secured on the right side of the easement above the lower sash, so that the sash-cords on may be drawn outwardly, so as to elevate the weights 0, thereby causing a slackness in said cords of a suflicient degree to allow the connected sashes to be swung inwardly, as shown in Fig.

To manipulate the sashes B C, so as to conveniently and safely cleanse them, the keeperstrip 4' and lower bead-sections c are released and folded away from the lower sash, as shown in Fig. The upper sash is now lowered to hook it upon the lower sash, and the lower sections of the parting-strips are retracted to release the lower sash, so that it may swing on its hinges p p. The two sashes are now swung together into the room and the exterior surface of the upper sash properly cleansed, and the interior-surface of thelower sash also. Said upper sash is then released from the lower sash and left to hang pendent, the lower sash being withdrawn by swinging it awayfrom the upper sash, which will expose the interior surface of the upper sash and the exterior surface of the lower sash, whichmay be readily cleansed while the operator is standing aside of the window in the apartment. \Vhen both sashes have been cleaned, as stated, they may be quickly restored to a closed position in the easement, the parting-strips projected, and then be slid in a vertical plane, as may be desired, the inner bead-strips of the window having been replaced by folding them and bolting them in place, so as to looselybear on the lower sash.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A window-casing having two verticallysliding sashes therein, provided with weights and cords to suspend and counterbalance the sashes, said weights moving in boxes of the casing, two hook-and-eye hinges for the lower sash that support it when in lowered adjustment from one side of the easement, hooks on the top edge of the upper sash, adapted to enter pockets on the upper edge of the lower sash when the upper sash is completely lowered, sectional parting-strips having their lower portions adjustable edgewise, sectional 3 5 bead-strips hinged on the stiles of the casement, and a keeper-strip hinged to the window-sill, all the hinged parts of the strips being adapted to fold toward the lower sash, substantially as described.

2. In a window, the combination, with a casing having outer bead-strips, sectional parting-strips that are movable edgewise in their lower sections, divided inner bead-strips hinged below to the window-casement, and a hinged keeper-strip on the sills inner edge, of two sashes that engage the casing between the strips, the lower sash having hook-and-eye hinged connection with a side of the casing when inlowered condition to swing inwardly, the upper sash having hooked connection with the lower sash when fully lowered, weights and cords which support and counterbalance the sashes, and a transverse camshaft in each side of the casing, which by rotative movement project or retract the parting-stri p lower sections, which they penetrate, substantially as described.

VALENTINE SCHIRMER.
